Poor Man's 220 MHz Receiver

Simplicity wins again with this easy-to-build receiver for local contacts on the 220 MHz band

In the August 73, I left the realm of sophistication to describe a simple, low power 220 MHz transmitter which lias enjoyed a remarkable performance record- Here is (he companion receiver—a two tube superregenerative unit which may be constructed 011 the same chassis as the transmitter. Perhaps you would prefer to listen to 220 lief ore building a transmitter, In that ease, try this inexpensive receiver with any small audio amplifier.

The "superregen" has a few disadvantages on a crowded band, but crowds are rare on 220. On the east coast, DX'ers congregate near 220 MHz with local club activity at 220.5 MHz and 221.4 MHz. This receiver will easily separate the major frequencies. A grounded grid preamplifier serves to increase the sensitivity of the receiver, and minimizes detector radiation to the antenna. The grounded grid configuration has the advantage of minimizing overload problems if yon live near a high power transmitter (such as or

Underside of the Poor Man's 220 MHz Receiver, As you con see, construction is very simple. This receiver was built os a unit, but it's easv to build the circuit into the transmitter.
